Why are OPEC still trading in dollars instead of Euros?
Answers:
They started using dollars until that time near be Euros and enjoy never changed, it is still the biggest international currency. It have historically be the most stable, newly not lately.
Would you trust the Euro (given that France is trying to cart over political control of the ECB) ?
The dollar have be around alot longer than the Euro even though OPEC's headquarters are contained by Vienna. OPEC stand for Organization of the Petroleum Exporting Countries so some do not trade using the EURO whereas adjectives the world trades using the dollar. Hope this help
